Title: Low cost battery charging systems
Inventor: CANTER STANLEY
IPC: H02J7/35
Filed: 2000-06-13
Abstract: A battery charging system that may advantageously be used to directly charge a battery of a spacecraft, for example. The battery charging system permits charging of battery without the use of power conditioners or dedicated charging arrays.  Primary and secondary solar array strings are coupled by way of a shunt regulator circuit to a power bus, such as a power bus of the spacecraft. A shunt regulator circuit is coupled to the secondary solar array string and to the power bus. Charge control relays are coupled between the secondary solar array string and the battery. A computer is coupled to the shunt regulator circuit and to the charge control relays.  Current from the secondary solar array string is used to charge the battery when the charge control relays are closed. If the computer determines that the battery is fully charged, the charge control relays are commanded open and current flows to the power bus unless shunted by the shunt regulator circuit. Fine control over the battery charge is achieved by adjusting the charging time and the number of circuits of the secondary solar array string that are connected to the battery.

Abstract: The invention relates to a levelling bar for coking ovens, for levelling the cones of discharged coal which form under the filling holes of the oven chamber during the filling process. The levelling bar consists of two cheeks, such as plates (1), which extend essentially over the entire length of the oven chamber and which are arranged at a distance from each other depending on the width of the oven chamber, and parallel to each other. They are also interconnected and are essentially vertical. The levelling bar also has transversal coal carriers (2) which are arranged in the intermediate space delimited by the cheeks (1) at a mutual distance, one behind the other and which only extend over part of the cross-sectional surface of the levelling bar formed between the cheeks (1). The height (3) of the coal carriers (2), which take up the entire interval between the cheeks, is less than the height (H) of the cheeks (1) and the cheeks form a gas channel (6) above the coal carriers (2) which is essentially free of built-in components.

IPC: A61B18/20
Filed: 1999-10-01
Abstract: Methods, and apparatus are disclosed for performing corneal ablation procedures of the eye (12) in a manner which does not interfere with the natural shape of the cornea or its orientation relative to the remainder of the eye, but which changes its surface curvature appropriately to achieve the required correction of vision. Three preferred embodiments are described, which model the cornea to different degrees of accuracy. Once the model of the cornea is obtained (610, 620, 630), surface curvature is modified (650) to achieve the degree of correction in refraction that is necessary, as determined by an eye test of the patient. The modified model of the cornea is then utilized to control the removal of material from the surface of the cornea in a corneal ablation operation.
